NQ HQ PQ core barrel head assembly
The head assembly provides: latching and pivoting spearpoint mechanisms to allow insertion and retrieval of the inner tube assembly, a bearing assembly to allow the inner tube to remain stationary and avoid sample damage while drilling, fluid pressure operating indications and fluid control valves. All head assemblies incorporate a shut off valve assembly which provides a fluid pressure signal to the drill operator when the valve members are compressed, indicating a full or blocked inner tube
TT Series Core Barrel Ultra-thin walled double tube core barrels, available diameters 46 and 56 mm. Very thin cutting face allows very rapid rate of penetration through hard formations.They are suitable for underground mining applications. |
---T2 Series Double Tube Core Barrels The T2 Series are thin wall double tube core barrel, used for surface exploration, especially mining applications. Due to their thin kerf, these core barrels provide rapid penetration. Available in diameters 46, 56, 66, 76, 86, 101mm. |
---T6 Series Double Tube Core Barrels These are a continuation of the T2 series, but of a sturdier design and available in larger diameters, 76, 86, 101, 116. 131 and 146mm. They are applied in surface mining and geotechnical drilling. |
---LTK 48 & LTK 60 Double Tube Core Barrels The LTK series core barrels system is a thinner wall core barrel than T2 series. They offer a cost effective, high production, which is designed for optimum production and core recovery in medium to extra hard rock formations. Available sizes 48 and 60mm. |
---WF Series Double Tube Core Barrels They are geotechnical core barrels primarily designed for coring relatively soft formations in using face-discharge bits. Simple construction and more resilient to damage than thin-wall barrels,but with slower enetration rate. |
---WG Series Double Tube Core Barrels There are Double tube core barrels for WG series. Available in DCDMA sizes E, A, B, N, and H. |
---TBW and TNW Core Barrels |
---Wireline Double Tube Core Barrels Wireline double core barrels are primarily used in deep coring. With an overshot device, they eliminate the need to couple and uncouple the rod string each time the core is retrieved. Available in DCDMA sizes A, B, N, H ,and P. |
